Sampathkumar Krishnan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20120116054
    Abstract: The invention provides, among other things, lyophilized compositions of high surface area that comprise a protein and that reconstitute quickly and efficiently to solution of high protein concentration with minimal formation, if any, of foam, effervescence, bubbles, turbidity, or particulates that might be deleterious. The invention also provides, among other things, methods for making the lyophilized compositions. The invention in additional aspects also provides Raman Imaging Spectrographic methods for real time analyses of polymorphs in a sample using PLS algorithms. By way of particular example, the use of the method for the analysis of mannitol polymorphs is described, and the use of the analysis to determine optimum compositions and lyophilization methods for producing lyophilates of pharmaceutical proteins having a predefined distribution of mannitol polymorphs and having the aforementioned reconstitution properties is also described.
